  7. //        The ScriptEditor OSAX. This is just a little sample
  8. //        that demonstrates how to read and write script files.
  9. //        It also executes scripts from inside the editor dialog
  10. //        or it can execute scripts with out displaying the dialog.
  11. //
  12. //        As always, bugs and comments to me at D.OLSON on Apple

  17. //        
  18. //        WARNINGS!!!
  19. //        This is untested code. I mean, I know it works
  20. //        but it's ugly! Scripts and comments are limited to 255
  21. //        characters. I didn't feel like adding TEdit to this thing.
  22. //
